IMPROVEMENT IN GAS-BURNERS.

TOALLIWHOM IT MAY CONOERN:

Be it known that I, CrIARLES S. FORD, of the city and county of Philadelphia, in the State of Pennsylvania, have invented anew and useful Improvement in Gras-Burners and I do hereby declare that the following is a full and exactdescription of"my invention, reference being had 'to the accompanying drawings making a. part of this specification, and whichshow a sectional elevation of my improved burners. A

The object of,l my invention is to provide a gas-burner that can be turned and placed in any desirable position without any escape of gas, andwhich, by means of a certainv and very simple eontrivauce, will enable those who use it to regulate at will the quantity of gas burned.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe its con` struction and operation. v

`A is the body of the burner, screwed in BV on the gas-fixture, as any ordinary burner; A is therefore indexible, and remainsvinvariably, as shown in the drawing, vertical. Part A of the body A is made tapering, and bears a round nut, N, A passing up through nut N, which is held in proper place, viz, presenting in therotarymovement to go up, by riveted head R. Nut N is made 'with a projection, P, on one of'its sides, on which fits burner B U, said burner being there secured by riveted head RiR. I thus obtain a gas-burner completely articulated, viz, which can revolve horizontally around A by means of nut N, and'vertically around P-by means of B U. Part B U of my rburner could be made out of one solid piece of metal, but as it is riveted on P at R', if the head B U of the' burner becomes worn out, it would give a great dealof trouble to file the rivet olf to chan-ge B lU, to avoid whih trouble I make my' burner in two piecesB/'U and B U-, as shown in the drawings. The gas, entering the body A of the burner at B, follows the arrows marked on drawing, and in the usualway reaches the head B U of the burner. i

A groove,-G, is made all around A', and two holes, H and II', are bored through and through at right angles through-A', therefore, in whateverposition nut N may be placed, the gas will always be allowed to continue its course up to B U. Asimilar disposition of.groove Gr and holes Il" and H" is made on P, and for -the same object. Now 'a female thread is cut in A', and in said thread sets the male flat-head ,screw s c, which -is made long enough to see that when it is screwed enough down to have its heads on or near R, it, the screw, will stop thegas in Xand prevent its reaching the holesII and II.V Therefore, if screw s c is so as t 0 obstruct only part of holes H and Hf, it will electually' 'diminish -the amount of gas allowed to reachl U.. Again, one of my objects in using screw s c is to obtain a regulator'of theI quantity of gas to be burned Onl gas-lights used in private rooms, where the parties can or should be trusted with the quantity of gas they may like to burn, I use a screw with a Iiat head, as has been above described. But when, for some partieular purpose, it is desired that one person should control and regulate, without interference, the amount of gas to be consumed, fthe head of my screw s c is then made square, as shown in s e, iig. 2, and a small handle or wrench, II A, permits to screw s c up or down-to suit the intended purpose, and when the wrenehis removed the s'erew cannot be regulated by other parties not in possession of the handle. Instead of'a wrench, a round head, with a square hole, fitting the head of s c, as 'shown in-Iig. 3, can be used.

Ido not intend to claim broadly the invention of an articulzited joint, but-I intend claiming the application of said articulation to gas-burners. I y i Having thusdescribed my invention, what I claim as my invention, and desire to secure by Letters Patent ofthe United States, isl I'. The application totgas-burners of a. universal articulated joint, composed-of body A, nut N, and projection P, burner B and head of 'burners-B-l U', the whole constructed and operating in the manner and for thepurpose set forth and described. i

i 2. The peculiar, construction of body A, combined with screw sc, for. the purpose above described and set forth.
